Fields
`kind`	`string` [Output Only] Type of the resource. Always `compute#subnetwork` for Subnetwork resources.
`id`	`string (uint64 format)` [Output Only] The unique identifier for the resource. This identifier is defined by the server.
`creationTimestamp`	`string` [Output Only] Creation timestamp in RFC3339 text format.
`name`	`string` The name of the resource, provided by the client when initially creating the resource. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
`description`	`string` An optional description of this resource. Provide this property when you create the resource. This field can be set only at resource creation time.
`network`	`string` The URL of the network to which this subnetwork belongs, provided by the client when initially creating the subnetwork. This field can be set only at resource creation time.
`ipCidrRange`	`string` The range of internal addresses that are owned by this subnetwork. Provide this property when you create the subnetwork. For example, `10.0.0.0/8` or `100.64.0.0/10`. Ranges must be unique and non-overlapping within a network. Only IPv4 is supported. This field is set at resource creation time. The range can be any range listed in the Valid ranges list. The range can be expanded after creation using `expandIpCidrRange`.
`reservedInternalRange`	`string` The URL of the reserved internal range.
`gatewayAddress`	`string` [Output Only] The gateway address for default routes to reach destination addresses outside this subnetwork.
`region`	`string` URL of the region where the Subnetwork resides. This field can be set only at resource creation time.
`selfLink`	`string` [Output Only] Server-defined URL for the resource.
`privateIpGoogleAccess`	`boolean` Whether the VMs in this subnet can access Google services without assigned external IP addresses. This field can be both set at resource creation time and updated using `setPrivateIpGoogleAccess`.
`secondaryIpRanges[]`	`object` An array of configurations for secondary IP ranges for VM instances contained in this subnetwork. The primary IP of such VM must belong to the primary ipCidrRange of the subnetwork. The alias IPs may belong to either primary or secondary ranges. This field can be updated with a `patch` request.
`secondaryIpRanges[].rangeName`	`string` The name associated with this subnetwork secondary range, used when adding an alias IP range to a VM instance. The name must be 1-63 characters long, and comply with RFC1035. The name must be unique within the subnetwork.
`secondaryIpRanges[].ipCidrRange`	`string` The range of IP addresses belonging to this subnetwork secondary range. Provide this property when you create the subnetwork. Ranges must be unique and non-overlapping with all primary and secondary IP ranges within a network. Only IPv4 is supported. The range can be any range listed in the Valid ranges list.
`secondaryIpRanges[].reservedInternalRange`	`string` The URL of the reserved internal range.
`fingerprint`	`string (bytes format)` Fingerprint of this resource. A hash of the contents stored in this object. This field is used in optimistic locking. This field will be ignored when inserting a `Subnetwork`. An up-to-date fingerprint must be provided in order to update the `Subnetwork`, otherwise the request will fail with error `412 conditionNotMet`. To see the latest fingerprint, make a `get()` request to retrieve a Subnetwork. A base64-encoded string.
`enableFlowLogs`	`boolean` Whether to enable flow logging for this subnetwork. If this field is not explicitly set, it will not appear in `get` listings. If not set the default behavior is determined by the org policy, if there is no org policy specified, then it will default to disabled. This field isn't supported if the subnet `purpose` field is set to `REGIONAL_MANAGED_PROXY`.
`privateIpv6GoogleAccess`	`enum` This field is for internal use. This field can be both set at resource creation time and updated using `patch`.
`ipv6CidrRange`	`string` [Output Only] This field is for internal use.
`externalIpv6Prefix`	`string` The external IPv6 address range that is owned by this subnetwork.
`internalIpv6Prefix`	`string` The internal IPv6 address range that is owned by this subnetwork.
`purpose`	`enum` The purpose of the resource. This field can be either `PRIVATE`, `GLOBAL_MANAGED_PROXY`, `REGIONAL_MANAGED_PROXY`, `PRIVATE_SERVICE_CONNECT`, or `PRIVATE` is the default purpose for user-created subnets or subnets that are automatically created in auto mode networks. Subnets with purpose set to `GLOBAL_MANAGED_PROXY` or `REGIONAL_MANAGED_PROXY` are user-created subnetworks that are reserved for Envoy-based load balancers. A subnet with purpose set to `PRIVATE_SERVICE_CONNECT` is used to publish services using Private Service Connect. If unspecified, the subnet purpose defaults to `PRIVATE`. The `enableFlowLogs` field isn't supported if the subnet `purpose` field is set to `GLOBAL_MANAGED_PROXY` or `REGIONAL_MANAGED_PROXY`.
`role`	`enum` The role of subnetwork. Currently, this field is only used when purpose is set to `GLOBAL_MANAGED_PROXY` or `REGIONAL_MANAGED_PROXY`. The value can be set to `ACTIVE` or `BACKUP`. An `ACTIVE` subnetwork is one that is currently being used for Envoy-based load balancers in a region. A `BACKUP` subnetwork is one that is ready to be promoted to `ACTIVE` or is currently draining. This field can be updated with a `patch` request.
`state`	`enum` [Output Only] The state of the subnetwork, which can be one of the following values: `READY`: Subnetwork is created and ready to use `DRAINING`: only applicable to subnetworks that have the purpose set to `INTERNAL_HTTPS_LOAD_BALANCER` and indicates that connections to the load balancer are being drained. A subnetwork that is draining cannot be used or modified until it reaches a status of `READY`
`logConfig`	`object` This field denotes the VPC flow logging options for this subnetwork. If logging is enabled, logs are exported to Cloud Logging.
`logConfig.enable`	`boolean` Whether to enable flow logging for this subnetwork. If this field is not explicitly set, it will not appear in `get` listings. If not set the default behavior is determined by the org policy, if there is no org policy specified, then it will default to disabled. Flow logging isn't supported if the subnet `purpose` field is set to `REGIONAL_MANAGED_PROXY`.
`logConfig.aggregationInterval`	`enum` Can only be specified if VPC flow logging for this subnetwork is enabled. Toggles the aggregation interval for collecting flow logs. Increasing the interval time will reduce the amount of generated flow logs for long lasting connections. Default is an interval of 5 seconds per connection.
`logConfig.flowSampling`	`number` Can only be specified if VPC flow logging for this subnetwork is enabled. The value of the field must be in [0, 1]. Set the sampling rate of VPC flow logs within the subnetwork where 1.0 means all collected logs are reported and 0.0 means no logs are reported. Default is 0.5 unless otherwise specified by the org policy, which means half of all collected logs are reported.
`logConfig.metadata`	`enum` Can only be specified if VPC flow logs for this subnetwork is enabled. Configures whether all, none or a subset of metadata fields should be added to the reported VPC flow logs. Default is `EXCLUDE_ALL_METADATA`.
`logConfig.metadataFields[]`	`string` Can only be specified if VPC flow logs for this subnetwork is enabled and "metadata" was set to CUSTOM_METADATA.
`logConfig.filterExpr`	`string` Can only be specified if VPC flow logs for this subnetwork is enabled. The filter expression is used to define which VPC flow logs should be exported to Cloud Logging.
`stackType`	`enum` The stack type for the subnet. If set to `IPV4_ONLY`, new VMs in the subnet are assigned IPv4 addresses only. If set to `IPV4_IPV6`, new VMs in the subnet can be assigned both IPv4 and IPv6 addresses. If not specified, `IPV4_ONLY` is used. This field can be both set at resource creation time and updated using `patch`.
`ipv6AccessType`	`enum` The access type of IPv6 address this subnet holds. It's immutable and can only be specified during creation or the first time the subnet is updated into IPV4_IPV6 dual stack.
